SPECIFICATION forming part of Letters Patent No. 531,605, dated December25, 1894. Application filed November 13,1893. Serial No. 490,839. (Nomodel.)

To all whom it may concern.-

Be it known that we, CHARLES W. WAR- -NER, of Melrose, county ofMiddlesex, and

GEORGE A. CRANE, of Worcester, county of Worcester, State ofMassachusetts, have invented a'n Improvement in Cultivators, of whichthe following description, in connection with the accompanying drawings,is a specification,like letters and figures on the drawings representinglike parts;

This invention has for its object to improve the construction ofwheel-hoes, or cultivators, whereby the hoes or cultivator teeth orother tools which may be employed, may be adjusted vertically, and alsopitched at different angles; and also whereby the wheel or wheels may beadjusted with said tools or independently, together with the vine guardor guards which may be connected therewith.

. Figure 1, shows in plan view a wheel-hoe or cultivator embodying thisinvention, the handles and vine guards being broken off to save space onthe drawings; Fig. 2, a side elevation of the wheel-hoe shown in Fig. 1;Fig. 3, a cross section of the wheel-hoe shown in Fig.

1, taken on the dotted line 00-00, on a smaller scale, the tools beingbroken off at their shanks; Fig. 4, a detail showing a portion of theadjustable frame carrying the wheel; Fig. 5, a detail showing thebearing for the wheel. Fig. 6,is a side View of amodified form of wheelhoe. Fig. 7, is a plan view of the wheel hoe shown in Fig. 6; Figs. 8and 9, side and plan views respectivelybf a modified form of adj ustableframe for the wheel; Figs. 10 and 11, side and plan views of amodified,form of ,wheel-hoe or cultivator, showing a single wheel.

The handle bars a, ct, are provided at their lower ends with likemetallic end pieces a each having a transverse bolt hole through it,near its extremity, said parts constituting the essential elements ofthe main or handle frame. An arched frame b, made as an independentpiece is secured to said end pieces 0. by the bolts which pass throughthe bolt holes therein, said arched frame being provided at each sidewith a slotted extension I), which project horizontally in oppositeways. To provide for vertical adjustment of saidindependent arched frameI), it is herein represented as havingat each side several bolt holes 2,arranged one above the other, three being herein shown,either pair ofwhich may receive the attaching bolts.

The hoes c, or cultivator teeth or other garden tools, are bolted ordetachably connected in any desirable way to the slotted extensions b,as for instance the shanks c of said tools or tool holders, may projectup through the slots, and their upper ends supplied with nuts 0 They maythus be moved so as to occupy different positions relative to theirsupporting frame.

A link d is loosely connected at its forward end to the top of thearched frame 17, and its opposite end is slotted as at d, and a crosspiece 01 is connected to and between the handles a, a, which is providedwith a thumb screw or bolt 02 which passesthrough the slot (1 in thelink (Z. By loosening said thumb bolt (i the link at may be movedlongitudinally, to thereby move the arched frame I) on its attachingbolts as pivots.

Theangles or pitch of the hoes c, cultivator teeth or other garden toolswhich are connected with the arched frame, are thereby changed.

The link 01 and thumb screw constitute a retaining device for retainingthe pivoted arched frame at any angle, or in any different position thatit may be set, and we desire it to be understood that so far as ourinvention is concerned any other specific form or construction ofretaining device may be employed in lieu of thatherein shown, and comewithin the spirit and scope of this invention. Said link however may beomitted if desired, and the arched frame b held in its vertical positionby the attaching bolt or otherwise, but in such instance verticaladjustment only will be afiorded for said arched frame, pro- Theinterposed block a is bolted or other wise detachably connected to thelateral extension b of the tool-carrying frame, it being hereinrepresented as having a shank portion a see Fig. 4, which passes upthrough the slot in said lateral extension I), and supplied'with a nutfor securing it in place.

The interposed block or piece a has a rearward and upwardly turnedextension 6 provided with a diagonal slot 6 near its extremity, and thearms e e have each like rearward and upwardly turned extensions e, andthe bolt e passes through said extensions c and through the slot a andwhen the nut is tightened the said extensions are firmly securedtogether with the interposed block between them.

By securing the extensions together, with the bolt e at different pointsof the slot 6 it will be seen that different elevations will be given tothe forward ends of the arms e e Thus it will be seen that the groundwheel e is detachably connected with the slotted tool-carrying frame;that it may be raised or lowered with relation thereto by the adjustingdevice just described; that it may be adj usted vertically bodily inconjunction with said frame; that it may be tilted bodily with saidframe; and that it may be moved laterally in the slot in the extensionb.

It is obvious that one of the arms a may be omitted, if desired, twobeing employed for strength and durability.

The interposed block a has a scraper or cleaner 6 formed upon it whichterminates adjacent the wheel 6.

Instead of the particular form or construction of adjusting device forthe wheel supporting arms e e above described, the form shown in Figs. 8and 9, may be employed. Referring to said figures, the arms e a arepivotally connected at their rear extremities as at e to the interposedblock a and the slot e ,ir 1 said block e is formed between the pivot 6and the wheel 6, and the bolt e joins the arms e e together passingthrough said slot in a mannersimilar to that heretofore described. Inthis latter form the scraper or cleaner will be provided on theinterposed block 6 substantially as above described.

The result accomplished by the two constructions is substantially thesame.

In case independent adjustment of the wheel e is not desired, it may besupported as shown in Figs. 6 and 7, wherein it will be seen that thearm a, is formed as a part of the main or handle frame, being formedintegral with the end pieces a and in such case the scraper or cleaner emay be formed integral therewith also.

The vine guard m has a hole through it at its rear end to receive theshank of the bolt 6 upon which it turns as a pivot, and the face of saidguard adjacent the supporting arm, as well as the face of saidsupporting arm are each provided with projections or S61 rations adaptedto interlock, so that as the forward ends of the vine guard are raisedor lowered in the arc of a circle about the bolt e as a center, and thenut on said bolt is tightened, it will be held securely in anypositionin which it may be set. Thus adjustment is obtained for the vineguard.

We are aware that an adjustable vine guard is not broadly new, but sofar as we are aware we are the first to adjust the same on a pivot orcenter.

In single wheel hoes the arched frame may be omitted, although the wheela may be supported by the adjustable supporting arms as herein shown.

Referring to Figs. 10 and ll,asingle wheelhoe is shown, the wheel beingsupported by a frame as in Figs. 1, 2, 4, 8, and 9, said frame beingsupported by a slotted tool-carrying frame to which the handles a, a areattached.
